Application June 24, 1935, Serial No. 28,168 2 Claims. (01. 123-21) The present invention relates to improvements in air cleaners and more particularly to air cleaners adapted to supply clean air to internal combustion engines of automobiles and the like.

An object of the invention is to provide a device for removing all dust at all speeds of the motor from the air entering the carburetor Without afiecting the air supply to the carburetor.

, A further object of the invention is to take advantage of the air which is drawn through the radiator by the fan for cooling the motor and to increase the compression in the cylinders by putting an increased. amount of mixture therein.

A further important object of the invention resides in the provision of an air cleaner of this nature which is comparatively simple in its construction, inexpensive to manufacture, thoroughly efiicient and reliable in use, and otherwise Well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of a device embodying the features of my invention showing portions of an internal combustion engine in dotted lines such as the carburetor, fan, cylinder head etc.

Figure 2 is a front elevation thereof.

Figure 3 is a vertical longitudinal section therethrough taken substantially on the line 3-3 of Figure 2.

' Figure 4 is a horizontal longitudinal section taken substantially on the line 4- 3 of Figure 1.

Referring to the drawings in detail it will be seen that numeral 5 denotes a cylindrical body having a flared front end 6 and a rear end i slightly increased in diameter. Numeral 3 de- 45 notes a cap of cylindrical construction the front end of which is adapted to fit in the rear end i and the rear end of this cap is in the form of a section of a sphere as indicated at 9 and has a plurality of apertures it! therein which are 00 closed by a plate H on a bolt i2 slidable through the center of the end 5 and having a spring id cooperably associated therewith for normally holding the plate H closed. This spring is of a comparatively Weak tension. Across the bot- 55 tom of the open end of the cap 8 is a wall I 5 forming a reservoir for oil or the like as indicated at it. A curved deflector or balile I1 is mounted in the body 5 and is adapted to extend over into the cap 8 as indicated to advantage in Figure 3. Under this bafiie there extends into 5 the body 5 a tube It adapted to be engaged in or over the air inlet of a carburetor. I

In operation the air enters the front of the body and is forced into the same by the fan of the engine and the speed of the car, the deflecl0 tor or bafile ll deflects the air to the top of the body and cap 8 and it is deflected against the rear of the cap and down over the oil l6 and is forced into the carburetor intake through the tube It. At high speed this cleaner will force 15 more air into the carburetor than is needed if it were not for the spring actuated closure plate ii. The spring is of such tension as to provide a comparatively even pressure at all speeds. In practical operation it has been noted that this 20 air cleaner lowers the partial vacuum on the pistons on their intake stroke, increases compression by putting an increased amount of mixture in the cylinders, decreases the oil passing the piston ring by decreasing the partial vacuum on 25 the intake stroke, lowers gasoline consumption by decreasing the partial vacuum created in the carburetor intake manifold, smooths out motor vibration, cleans the air taken into the motor and keeps the air pressure on the carburetor 3O constant at all speeds.

It is thought that the construction, operation, utility and advantages of this invention Will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the de tails of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is:

1. An air cleaner of the class described comprising a cylindrical body open at both ends, a cap for closing the rear end of the body, a tube extending through the bottom of the body, a deflector in the bottom of the body curved to extend over the top of the tube and into the cap,

said cap having a wall across the open end thereof at the bottom to provide an oil reservoir.

2. An air cleaner of the class described comprising a cylindrical body open at both ends, a cap for closing the rear end of the body, a tube extending through the bottom of the body, a deflector in the bottom of the body curved to extend over the top of the tube and into the cap,

said cap having a wall across the open end thereof at the bottom to provide an oil reservoir, the rear of the cap being perforated, a plate for closing the perforations, and spring means associated with the plate for normally holding it 5 closed.
